. Specification of Letters Patent.

Patented Dec. 8, 1914.

Application filed February 26, 1914. seria N... 821,253..

. To all whom it may concern:

' tenors, of which the following isa specification, reference being had to the accompany ing drawlngsa This inventlon relates to new and useful improvements in cardoors and more particularly to an improvedfastener therefor, the main object of the invention being the provision of a fastener which 1s particularly adapted to sliding car doors and is so arr ranged that the door cannot beloclred until the same is in an entirely closed position.

A. still further object of the invention is the provision of a sliding door fastener which will possess advantages n points of eliiciency and durability, is lnexpensive to 'manufacture and, at the same time, is siniplein construction and operation.

iVith the above and other ob ects in view, the invention OOIlSlStS 1n the novel features of construction, combination and arrangement of parts as willbe hereinafter referred toand more particularly pointed out in the specification and claims. a

In the accompanying drawing forming a part of this application, Figure 1 is a front elevation of a car door constructed in accordance with my invention, Fig. Qis a longitudinal sectional view taken upon the line 2-2, Fig. 1. Fig.3 is a top plan view of the movable locking bar. Figh l is a transverse sectional view taken on the line 4--4, Fig. 1; and Fig. 5 is a transversesectional view of the looking bar.

Referring more particularly to the drawings, the numeral 8 designates a car door and disposed in a vertical position, are the stop rails 9 andlO, the rail 9 being arranged along one of the longitudinal side edges of the door opening 2, while the rail 10 is ar- 1 ranged at a point removed from the opposite or longitudinal side edge of the opening, and at a distance which is substantially the same as the Width of the door and is adapted to limit the sliding movement of the door when the same is opened. In order to retain the door against swinging movement when the same is moved to open position, I provide a retaining plate 11, one end of which is rigidly secured tothe car and stop rail, While the other end thereof projccts beyond the inner face of the stop rail 10 and engages overthe outer face ofwthe.

door.

The top 5 when in its closed position isrig ber which is generally indicated by the.

numeral 13 and which is substantially rectangularln form, havlng one of its side edges thereof rounded, as shown at 14 to permit rotation of the same, without engagmg with the car body. The ends of the locking member 13 are provided with spin-v dles 15 suitably mounted within bearings 16, arranged upon opposite sides of the door opening at the lower end thereof, whereby said locking member maybe readily rotated to engage or disengage the same over the lower end of the door. One side of the lockingmember is provided with a longitudinal recess 17 which forms an engaging flange 18 which, when the locking member is in its locked position, engages overthe lower edge of the door to securely hold the same against outward swinging movement. Theolosed ends of the recesses, which are indicated by the numeral 19 retain the door against any sliding movement whatsoever.

The locking member is provided at one end with a cutaway portion, as shown at 20. which Pl'OVlClQS a shoulder 21, with which the catch 22 is adapted to engage to prevent rotary movement of the locking member.

The locking plate 23, upon which the catch.

outwardly and having its other end dis posed at right angles and provided with an opening 241:. The looped end of theplate extends upwardly beyond the catch 22 to reinforce said catch member, as indicated in Fig. 41;. Secured to the car body and arranged at the lower end of the stop member 9, is a plate 25 having formed thereon the outwardly projecting perforated cars 26 in which is slidably mounted a locking bolt 27, the lower end of said bolt being adapted to engage within the opening 2 1 to retain the locking plate 23 in its effective position so that the catch member 22 will engage the shoulder 21 and hold the locking member 14 against rotation.

From the above, it will be apparent that the door member 5 will be securely held 1O limiting the sliding movement of the door.

it will be apparent from the foregoing description that l have provided a simple and durable car' door which is mounted for sliding and swinging movement whereby should the I contents of the car become jammed against the door during transportation, the door may be readily opened, without injuring the same or the fastening means, which support the door, or without tearing the door from its fasteners. It will also be apparent that the door cannot be locked in its effective position, untilv the same is entirely closed, thus preventing the slatting or nailing of the door in a partly closed position. It will be apparent that my improved car door and fastening means may be quickly and readily applied to any of the well known forms of freight cars now in use and, at the same time, is simple in construction and can be manufactured at a comparatively low cost.

While l'have shown and described the preferred form of my invention, it will be obvious that various changes in the details of construction and in the proportions may be resorted to for successfully carrying my invention into practice, without sacrificing any of the novel features or departing from the scope of the appended claims.

Having thus described this invention, what I claim is 1+ 1. A device of the class described including a door mounted for sliding movement, a

Copies of'thixs patent may be obtained for rotary locking member provided with a longitudinal recess, a flange formed continuous with the recess and adapted to engage over the lower edge of the door, the ends of said recess being closed to prevent lateral movement of the door when the locking member is in its effective position, and means for retaining said locking member in its effective position.

2. A device of the class described including a car door mounted for sliding movement, a locking member mounted for rotary movement and having a longitudinal recess formed therein, a flange formed continuous with the recess and adapted to engage over the lower edge of the car door, said recess having its ends closed to prevent lateral movement of the door, one end of said locking member having a recess providing a shoulder, a pivotally mounted locking plate having'a catch adapted to engage said shoulder when the locking member is in its efiiective position, and means for retaining said catch in engagement with the shoulder.

3. A device of the. class described including a car door mounted for sliding movement a rotary locking member having a longitudinal recess in one end thereof providing an engaging flange adapted to engage the lower edge of the door, flanges formed upon each end of said locking member, one end of said locking member having a recess forming a shoulder, a locking plate rotatably mounted upon one of said flanges and having a catch adapted to engage said shoulder when the plate is in its locked position, and means engaging one end of the plate to retain the same in its effective position. 1
